Aerox Oxygen System 2M - 22 Cubic Feet Cylinder

Part# 13-18902
MFR Model# 500R2M


Note: All systems include flowmeters and cannulas and require refilling adapter unless at an airport.

Prior to the introduction of the Aerox system, wise pilots reserved the use of oxygen for situations where it was legally necessary, i.e. above 12,500 ft. This was often a practical decision based upon factors like: Short duration of supply, uncomfortable masks, difficult & costly refills, heavy weight and large bulk. Aerox systems address these objections with advanced designs and materials that help make oxygen use easier, more comfortable, and less expensive than ever before. Add to your flying comfort by using oxygen at altitudes as low as 5000 feet.

Aerox Oxygen Systems include lightweight aluminum cylinders, regulators, all hardware, flowmeter, and nasal cannulas (masks available as an option). Oxysaver oxygen saving cannulas and Aerox Flow Control Regulators increase the duration of oxygen supply about four times, and prevent nasal irritation and dryness. The Emergency Oxygen Packs are lightweight aluminum, refillable, & have no life limit. Just put on the mask and open the valve; no adjustment is needed. Complete brochure available on request.

Q: I recently purchased an AEROX 2M-22 system (Aircraft Spruce part # 13-18902, AEROX Part # 2M-500). Please confirm the filling adapter to a 540 tank valve (I think it is the FA-PB3).

Yes the FA-PB3 would be correct.

You would want our part number 13-18906 which is the same system but set up for 4 people.

Q: Hello, a few questions: br 1)Size of the cylinder? br 2)Is the bag included? I see it in the picture. br 3)Does the system beep when sending oxygen to inhale? br 4)What type of regulator?

The tank is 5.25 in diameter and 16.5 tall and 21.25 total with the regulator. The bag is not included, you would want part number 13-18990-M for this tank. There is not a beep or alarm and it uses a low pro, fixed flow CGA540 regulator.

The bottles are the same, 2M has connections for two people an 4m is for 4.
